Application filed January The invention relates'to operating means for roller awnings and has for its object to provide a coordination of driving and driven gears associated withbearing block in which the end of the roller is journaled, said block being pivotally supported in a bracket having bearing slot to receive the pintle of the bearing block, said slot having a depression therein to be normally engaged by m the pintle to cant the bearing block out of the vertical and cause the driving gear car- Fi 3 are o'ers ective detail views of the 2 bracket and detent.

Referring to the drawings, 1 indicates the usual form of roller comprising a hollow tube, which is revolved ;toroll and unroll the awning fabric. Fixed to the end of the roller is a bevel-gear 2 by means of which the rotation of the roller in either direction is effected. The endof the roller is jour naled on a pintle extending laterally from a bearing block 3, which latter is provided with a flanged boss or pintle 5 on its opposite face, which pintle is provided with fiat sides 6. This pintle engages an open bearing slot 8 in the forward end of a bracket 7, which latter may be of any suitable form or construction and is adapt-ed to be secured to the wall or other support of the awning. The slot 8 is provided with a depression 9 in its forward portion, which form a step with the rear portion of the slot upon which one of the fiat faces 6 of the pintle 5 rests in such relation as to cause the bearing block 3 to be canted from the vertical. f

The bearing block is provided with a longitudinal bore in which is journaled the reduced upper end 17 of the hollow hub 16 of a driving bevel-gear 15, said hub being serured in position by a cross pin or bolt 18,

which engages the upper face of the bearing,

block, said driving gear 16 meshing with the 60 awning.

The lower portion of the hub 16 of the driving gear is provided with opposite bayogear 2 on the roller 1 to rotate said roller in the operation of rolling or unrolling the 6, 1937, Serial No. 15933 net slots 19, to receive the ends of cross pin 21 on the endof'an operati-nghandle 20,, preferably provided with a crank handle 2 i i 4 which is Bolted to the bracket" 7 is detent 1O,-I

locked against rotation in the slots 19 in the lower end of the hub. The

operator then moves the handle 20 to substantially vertical position, which has the effeet of swinging pintle 5 to cause disengaged from the bearing block 3 on its the driving gear 15 to be the detent 10 and permitting the driving gear to be rotated by the handle, and

said driving gear rotates thev roller 1 through the gear 2 connected therewith, to roll or unroll the awning according to the direction After the awning of rotation of the handle. has been rolled or unrolled to the desired extent, the operator releases the handle 20, thereby permitting the pintle 5 of the bearing the depression 9 of the ing bracket, the

block to rock forward into slot 8 of the supportreby canting the bearing block from the vertical and causing the driving gear 15 to again engage detent 10.
